Throughout 2017, Minnesota Public Radio will celebrate 50 years on the air by sharing highlights from our archives, connecting Minnesota's past to its present. | This conversation and call-in show with playwright August Wilson originally aired on Sept. 18, 1989, on MPR News' Midday program, hosted by Stephen Smith.

Among the nominees for Best Picture at next Sunday's 89th Academy Awards is "Fences," a drama set in Pittsburgh and based on a play by two-time Pulitzer Prize-winner — and former St. Paulite — August Wilson.

The film has been nominated for four Oscars: Best Picture; Best Actor, for Denzel Washington's role as Troy Maxson; Best Supporting Actress, for Viola Davis' role as Rose, Troy's wife; and Best Writing for an Adapted Screenplay, for Wilson.

Wilson, who died of liver cancer in 2005, wrote plays that explored the impact of African-Americans' migration from the rural South to northern cities in the early 1900s — and the inequities they faced once they got there.

"I think that it was with great energy and great hope that blacks first came north in early 1916, 1920, 1930, searching for a better life than they had in the South," Wilson told MPR News host Stephen Smith in a 1989 conversation. "Given the historical perspective, we can look back now, in 1989 — we can look back 50, 60 years — and these cities have not been hospitable."

During a speech at the University of Minnesota Alumni Association two years later, Wilson told the audience that, throughout his career, he experienced the effects of those inhospitable cities: People asked again and again when he would be done writing about the black experience — as if it were exhaustible. At the same time, he said, countless plays, books and movies continued to be released about the experience of white Americans.

The short list of African-American Academy Award winners over the years underscores his point.

The Oscars will be presented, once again, under the cloud of the #OscarsSoWhite controversy that surfaced at last year's ceremony. While the number of black honorees has grown significantly — 11 nominees for the 2016 awards, as compared to 2015's two — historically, black performers and artists have been largely overlooked at the annual award show.

Best Actor in a Leading Role

No black artist has ever won an Oscar for best cinematography, best costume design or best director. But this year, that could change: Bradford Young has been nominated for best cinematography for his work on "Arrival," and Barry Jenkins has been nominated for best director for the film "Moonlight."
